Introduction
Safety instructions
Except external power supply (230VAC), this equipment contains DC (3-12VDC) voltages.
Do not handle any metallic part until the 230VAC power supply has been disconnected! Do
not assemble, disassemble set when the power reminds switched ON. Making wiring and
touching cables is strongly prohibited when power is ON. Never work alone under hazardous
voltage conditions. Always check that the power cord(s), plug(s), and sockets are in good
conditions. Always use qualified service personnel to install permanently wired equipment
and surge antenna arrestors.
What is NTS-pico?
NTS-pico
is a complete, stand-alone, miniature NTP Time Server. Optionally it supports PTP
too. It works in Ethernet TCP/IP environment. It has been designed to provide a stable
UTC
(Coordinated Universal Time) synchronization, which possesses the long-term stability of
GNSS (Global Navigation Satellite System
) to small industrial local networks up to 10 PC.
The standard synchronization accuracy is level of hundreds of millisecond [ms] for LAN and
it is sub-tens of second [s] for Internet. Therefore,
NTS-pico
is not time instrument and should
not be use at scientific, laboratory or advanced IT synchronization environments
.
NTS-pico id dedicated for up 10 pcs networks
The NTS-pico GNSS receiver is designed for automatic operation without the need for user
intervention. It can however, be accessed via a serial port (rs232 or USB) for configuration
and debug purposes. If the satellite signal is interrupted, the NTS-pico enters a FREE RUN
mode. NTS-pico is not including internal OSC and therefore it is not supporting HOLDOVER
mode. When the GNSS signal is restored, the GNSS receiver automatically reverts to normal
operation mode. For this reason, it is important to continuously trace the performance of
GNSS signals and synchronization process. Following synchronization Ethernet protocols are
supported:
•
NTP Network Time Protocol (rfc5905)
•
SNTP Simple NTP (rfc 4330)
•
PTP Precision Time Protocol IEEE1588:2008 /extra option/
Referential UTC is drawn from GPS & Glonass via built-in Telit GNSS receiver, using
NMEA183 frame. NTS-pico does not support 1PPS frequency reference.
